Have you been to less developed countries? They just simply do not package some products. It removes a lot of the allure of buying particular things, but also generates less trash.
Here's a simple example: utensils. In some countries, you just buy the utensil. In America, you buy a box with utensils in them, sometimes with a plastic shell, sometimes with paper wrapping inside of the box. But without the box, it feels like you're buying them from the dollar store no matter how nice the actual spoons and knives are, which commands less of a price mark up.
